[QUOTE="cohunt, post: 1710718, member: 94491"] some times factory loads are waaaay short-- this "induced headspace" can cause "false" pressure signs such as flat primers, ejector marks, etc -- do you have a comparator to measure what the factory rem brass measures before and after firing? your pics are blurry for me, are those extractor marks or ejector marks? if they are ejector marks are they just marks or are they swipes? rem 700's are known to have oversize firing pin holes in the bolts which can cause a false "cratering" of the primer also factory brass is notorious for being under size too [/QUOTE]
